Will your coating stay put — or peel, flake, and fail in the field? The fastest, most recognised way to grade coating adhesion is the cross hatch test, where a lattice of cuts is scored into the film and rated by how much coating stays bonded. Looking for a dependable cross hatch tester in chennai, tamilnadu? Kiyo R&D Lab performs cross-hatch adhesion testing to ASTM and ISO methods and grades your coating with confidence.
From paints and powder coatings to primers, plating, and industrial films on metal or plastic, our expert team delivers clear adhesion ratings, supporting photos, and audit-ready reports you can rely on.
A cross hatch test grades how well a coating sticks to its substrate. A special cutting tool scores a lattice of parallel cuts at right angles through the film down to the base material; pressure-sensitive tape is applied over the grid and pulled off, and the amount of coating removed is rated against a standard scale. The equipment used — a cross hatch tester in chennai, tamilnadu — uses fixed, evenly spaced blades so the cut spacing is consistent and the result is repeatable.
It’s fast, low-cost, and widely specified — which is why it’s the go-to adhesion check for incoming inspection, production QC, and coating-failure investigations.

| ISO Grade | ASTM Grade | Result |
|---|---|---|
| 0 | 5B | Edges smooth, 0% removed — best |
| 1 | 4B | Small flakes at intersections, <5% |
| 2 | 3B | Flaking along edges, 5–15% |
| 3 | 2B | Flaking in strips, 15–35% |
| 4 | 1B | Large flaking, 35–65% |
| 5 | 0B | Removal greater than 65% — worst |
